[Request] Add support for modifying SPUI behavior through the SDK.

[nikii-me]

Many of the SPUIs in-game can be easily modified through props and other files in SporeModder FX, however some of the SPUIs functions seem to be hard-coded. The best example for this would be the file named SPGMissionCard.spui, for which strings and look can be easily modifed, but ex. modifying how many instances of this SPUI can appear on the screen is impossible at the moment. Also, the same .spui is used for tracking space stage badges, but functionality for those seems to be completely hard-coded.
In image below I simply swapped the textures to confirm the same .spui is used for both missions and badges, but that's as far as I could go in SporeModderFX besides moving pieces around and what-not.
